tools needed for disassembly? (MP7)

So i have an extended 6.03 tbb from Falcon and a [barrel extension] to cover it up. I cant seem to find what hex key will fit the safety selector and bolt catch lever to remove them. Anybody know what size tool is needed? Ive heard 1.3mm and 1mm, but i just want to be completely sure and hear it from someone with experience. Thanks in advance!

0.9mm allen wrench for the set screws in the fire selector and bolt release
1.5mm allen wrench for a few set screws that hold the barrel assembly to the main receiver
a punch. i usually use a 1/16 to punch out the trigger pin and another pin that holds the barrel onto the receiver
